Fix PR14161 - Check index being extracted to be constant 0 before simplfiying. Otherwise, retain the original sequence. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166504 91177308-0d34-0410-b5e6-96231b3b80d8

[x86] Regenerate a number of FileCheck assertions with my script for test cases that will change with the new vector shuffle lowering. This gives us a nice baseline for deltas against. I've checked and removed the cases where there were weird register usage being pinned down, and all of these are extremely pin-pointed tests so fully checking them seems very appropriate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218941 91177308-0d34-0410-b5e6-96231b3b80d8
